Corrected entry: In the opening sequence, Voyager is passing through a gas cloud. In this sequence Voyager is parting the gas and dust like it would if there was air around, there even are some turbulences near the warp nacelles. Voyager utilises a navigational deflector, which effectively cleans space in front of Voyager. The CGI in the opening sequence shows this only to be a few metres in front of Voyager's bow. How ever navigational deflectors form overlapping shield bubbles a few hundred meters in front of the ship, even at low impulse speed. Flying through such a cloud would even require engaging combat shields, which would form a bubble around Voyager bigger than leaving a few meters of space between the shields and the hull. Even if the shields weren't conformal to the hull there would be more space. Last but not least the navigational deflector would provide particles with a directional impulse straight away from the ship, and not letting it slide along the deflector. The displayed turbulences near the nacelles would be highly abrasive to the ship's hull.
Corrected entry: Voyager is often having to dim the lights are figure out ways to save energy by shutting down life support in various sections of the ship. Yet, they have energy for beaming up and down, and holodeck activities, and use of the replicators on a limiting basis. I don't feel like doing the math but the energy required to replicate a cup of coffee is certainly enough to light the ship for a long time.
Corrected entry: In the opening credits, Voyager is seen skimming along above the "surface" of the planetary rings of what appears to be a large planet. However, given the size of the reflection of the ship in the rings below, Voyager can be at most a few hundred meters above the reflective surface. That, coupled with the extreme curvature of the rings, and Voyager's path across them, would make the planet the smallest in the universe, perhaps a few thousand meters across. No moon or asteroid of that size would have enough gravity to capture and retain rings of rocky debris, much less possess an atmosphere that would be thick enough to see or have clouds.
Corrected entry: If Voyager is travelling in a fairly straight line at a fairly consistent speed (often Warps 6 through 9) why do they keep running into other recurring characters, such as Seska? Is everyone else just following Voyager around the Delta quadrant? In the same way, why does Nelix keep bumping into friends? Had his small ship (which was slower than Voyager) already travelled for several years in the exact same direction before?
